WILLIAM H. JANNEY, OF MARTINSBURG, WEST VIRGINIA.

GRAlN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 249,055, dated November1, 1881,

Application filed December 1, 1879.

To all whom it may concern:

Be it known that I, WlLLIAM H. J ANNEY, of Martinsburg, in the county ofBerkeley and State of West Virginia, have invented certain new anduseful Improvements in Grain-Scparators; and Ido hereby declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters of reference marked thereon, whichform a part of this specification, and in which-- Figure 1 is a planView of my improved thrashing machine. Fig. 2 is a longitudinal sectionof the same, and Fig. 3 is a detail view of the shakers.

My invention relates to an improvement in the class of grain-separatorswhich include a traveling endless-band elevator and a shaker or meansfor separating the cats from the straw and conveying the latter awayfrom the machine, while the grain passes downward and is winnowed by afan-blast.

My improvementrelatcs to the construction and arrangement of the partsby which the course ofthe falling grain and blast is directed, theresult attained being that the grain is more thoroughly cleaned, andwithout the aid of vibrating or other screens.

A in the accompanying drawings marks the feed-cylinder, and B the strawor grain elevator, with a series of transverse slats attached thereto.

0 is the fan, located in rear of an inclined board, D, with its upperend separated by a blast-passage, cl, from the under side of thegrain-elevator, and its lower end provided with a rearward extension,(1, separated from a rearwardly-extending board, d by a blastpassage,(1. The blast from the passage d acts upon the grain passing from theelevator B upon the shakers, while the blast from the passage d actsupon the grain returned from the shakers by the inclined board H, andescapes downward through the opening 01 E is the picker, disposed so asto take the grain from the elevator B and pass it upon the shakers. Theteeth of the picker are tangential to its periphery to permit the readyremoval of the grain, &c., therefrom, which fall upon the shakers.

F F are the shakers, two in number, and arranged each upon rolls 6 e,and so as to have a limited back-and-torward motion. These shakers areconnected to a double-crank shaft, G, which acts upon the said shakersso as to cause them to move simultaneously in opposite directions, andthus enable them to effect the separation of the grain falling thereon.These shakers are armed with teeth g g. The grain, after leaving theshakers, is returned upon an inclined board, H, and, falling upon theincline I) and within the mill, is subjected to a second blast, asaforesaid, and is then passed down through opening (1 into a suitablereceptacle, (not shown,) being first blown against the inclined board I,down Which it slides, while the chalf, short straw, antl other lightparticles are carried on by the blast over the top of the board.

The elevator B consists of a slatted apron, with the under side of theupper portion resting upon or passing over an imperforate surface orboard, as seen in Fig. 2, while to the under side of the machine arefastened boards h, to catch and conveniently hold any tine particles orrefuse matter passing off at that point.

Having thus fully described my invention, 1 claim and desire to secureby Letters Patent- The combination of the inclined board D, having thehorizontal portion (1, the horizontal part 61 having adownwardly-inclined front portion, and said part (1. being separatedfrom part 61 and from the base of the fan-box by narrow blast-spaces,the inclined guard-board I, separated from part 61 by opening (1 thefan, shaker F, and return-board H, all arranged as shown and described,whereby a portion of the blast acts on the grain as it falls from theshaker and return-board, another portion as it passes over boards D d (1and a third portion as itescapes downward into opening (1*, as setforth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of November, 1879.

WILLIAM H. J ANN EY.
